Answer:
Kindly check explanation
Step-by-step explanation:
1) shape = square
Side length = 6.5 in
Area of square = (side length)²
Area = 6.5^2 = 42.25 in²
Perimeter of square = 4 * side length = 4 * 6.5 = 26 in
2.) shape = rectangle
Dimension = 1.1 by 2.8m
Area of rectangle = Length * width = 1.1 * 2.8 = 3.08 m²
Perimeter of rectangle = 2(length + Width)
Perimeter = 2(1.1 + 2.8) = 2(3.9) = 7.8 m
3.) triangle
Base = 4.5 ; height = 6.5 ; hypotenus = 7.9 cm
Area = 0.5bh = 0.5 * 4.5 * 6.5 = 14.625 cm²
Perimeter = (4.5 + 6.5 + 7.9) cm = 18.9 cm

The shortest one is 1/4 foot. See how easy it is to be nice?
Represent
r=number of rabbits
c=number of chickens
1 rabbit=4 feet and 1 head
1 chicen=2 feet and 1 head
rabbits head+chicen heads=72
1r+1c=72
feet=200
4 times r+2 times c=200
4r+2c=200
divide both sides by 2
2r+c=100
we have
r+c=72
2r+c=100
make first equation negative and add to second equation
-r-c=-72
<u>2r+c=100 +
</u>1r+0c=28
r=28
subsitute
r+c=72
28+c=72
subtract 28
c=44
44 chickens and 28 rabits

Answer:
Step-by-step explanation:
x / 2.25 seconds = 28 times / 12 seconds
multiply by sides by 2.25 seconds
x / 2.25 seconds * 2.25 seconds = 28 times / 12 seconds * 2.25 second
x = 2.3333333 times/ second * 2.25 seconds
x = 5.8333
